  1. 1. Blågröna lösningar i en grå stadsdel

    Kandidat-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Matilda Hiller; Niklas Jönsson; [2024]
    Nyckelord :Blågrön infrastruktur; dagvattenhantering; regnbäddar; biofilter; svackdiken; permeabel markbeläggning; öppet förstärkningslager; växtval; Gåsebäck; Helsingborg;

    Sammanfattning : Vatten är livsviktigt för allt liv på jorden, men vad händer när vattnet istället för resurs blir en belastning? Stora andelar hårdgjorda ytor i kombination med skyfall kan skapa problem i städer. I miljöer med mycket asfalt eller betong, förändras vattnets naturliga kretslopp. LÄS MER

  3. 2. Metaller i Vombsjön - Mygglarver som bioindikator för miljöövervakning

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Siri Bengtsson; [2024]
    Nyckelord :Bioindicators; Chironomidae; Freshwater source; Lake Vomb; Metal concentrations; Pollution; Sediment sampling; Earth and Environmental Sciences;

    Sammanfattning : This study investigates concentrations of eight metals (Cu, Zn, Cd, Pb, Hg, Cr, Ni, As) in the freshwater resource Lake Vomb, located in the south of Sweden (Scania), and explores the potential use of deformed Chironomidae larvae as bioindicator. Sediment samples from six locations were analysed against threshold values from the Swedish Agency for Marine and Water Management and background values from the Swedish Environmental Protection Agency.

  4. 3. Hur avrinningskoefficienten varierar med återkomsttid - En jämförelse mellan fyra olika områden i Sverige

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Nina Enger; [2024]
    Nyckelord :Runoff coefficient; Return period; Modelling; MIKE ; Floodings; Technology and Engineering;

    Sammanfattning : As climate change progresses, heavy rainfall in Sweden is becoming more frequent and intense, coinciding with an increase in impermeable surfaces in urban areas. This raises the risk of flooding as drainage networks may exceed their capacity due to increased runoff. LÄS MER

  5. 4. Managing Domestic Wells in Sweden. Investigating the role of domestic wells in ensuring a reliable drinking water supply and assessing their vulnerability to climate change

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Alice Stenfelt; [2023-08-28]
    Nyckelord :Domestic wells; Individual drinking water supply; Climate change; Sustainable development; Drinking water management; resilience water supply; Climate adaption; Sweden;

    Sammanfattning : Domestic wells provide drinking water for a significant proportion of the population in Sweden, especially in rural areas where public water supplies are not available (Drage, 2022; Hjerne et al., 2021). Domestic wells typically lack regulation (Gunnarsdottir et al., 2020; Stoll et al. LÄS MER

  7. 5. If Trees Could Talk - Dendrochemistry, a Promising Method for Understanding Pollution History

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Jonatan Uusitalo; [2023-08-17]
    Nyckelord :;

    Sammanfattning : Heavy metal pollution presents a significant environmental challenge in the Anthropocene era, and understanding pollution history is crucial to address historical pollution and implementing effective mitigation measures. This study stands among a few comprehensive dendrochemical investigations that utilized an extensive dataset and energy dispersive X-ray fluorescence (EDXRF) technique to reconstruct the contamination history of As, Cd, Cu, Ni, Pb, and Zn, with a focus on Cu.
